Google Professional Cloud Network Engineer Question 764
Select 3Google Cloud PlatformYou have deployed a complex application in Google Cloud that involves multiple Compute Engine instances, a Cloud SQL database, and a Cloud Load Balancer. Users are reporting intermittent latency issues when accessing the application. You decide to use the Network Topology tool to diagnose the problem. Which of the following actions can you perform using Network Topology to identify potential issues?
- A
Visualize the traffic flow between your Compute Engine instances and the Cloud SQL database to identify bottlenecks.
- B
Monitor the latency and throughput between the Cloud Load Balancer and user devices to determine if there are performance issues.
- C
Simulate traffic flow changes to predict the impact of modifying network configurations.
- D
View historical traffic data to identify patterns or recurring performance issues.
- E
Directly configure firewall rules within the Network Topology tool to resolve detected issues.
Show answer and explanation
Correct answers: A, B, D
Explanation
The Network Topology tool in Google Cloud is a powerful visualization tool that helps you understand the flow of traffic, monitor latency and throughput, and analyze historical traffic data. It is particularly useful for diagnosing performance issues and identifying bottlenecks but does not allow direct configuration changes or traffic simulations.
- A. Correct.
Correct: Network Topology allows you to visualize traffic flow between components, such as Compute Engine instances and Cloud SQL, helping to identify bottlenecks.
- B. Correct.
Correct: Network Topology can monitor latency and throughput between components, including the Cloud Load Balancer and user devices, to help detect performance issues.
- C. Incorrect.
Incorrect: Network Topology does not provide the capability to simulate traffic flow changes. Such simulations require additional tools or services.
- D. Correct.
Correct: Network Topology provides historical traffic data, which can be useful for identifying patterns or recurring performance issues.
- E. Incorrect.
Incorrect: While Network Topology helps visualize network configurations, it does not allow you to directly configure firewall rules. Firewall rules need to be managed separately in the Google Cloud Console.
